Sinter Plant Baghouse
Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. The sintering process is a pre-treatment step in the production of iron, where fine particles of iron ores and also secondary iron oxide wastes (collected dusts, mill scale etc.) along with fluxes (lime, limestone and dolomite) are agglomerated by combustion.

The properties of dust from sinter plants require careful attention with regard to the design of the filter and selection of fabric filter material. Regarding the filter material, two types of malfunctions have to be considered: first: clogging due to continuous infiltration of the filter material by dust particles or condensing material, which results in an ongoing increase of the pressure drop and second: loss of break strength of the filter material, which results in damage of the filter bags and consequently increases the clean gas dust concentration
